SPECIFICATION forming lpart of Letters Patent N 0. 779,574, dated January 10, 190.5. Applicants tied June 17,1904. serial No. 212,939.

` To all whom it may concern: i Be it known that I JOHN O. BARBER, a citizenof the United States, residing at Chicago,

in the county oi"- Cook and State of Illinois,

5 .have invented certain new and useful Improvements in' Car-Trucks; and I do hereby declare the `'following to be full, clear, and 4erntet description of the invention, s'uch aswill enable others skilled in the art to which it appertains ,IC to make and use thesarne.

ticularly to car-trucks of the type known to the,tradeas the Barber lateral-motion truck. l Y 1.5 A The present invention'has for,its especial I object to improve the devices which support lthe bolster with freedom for limited endwise movements transverselyof the truck.

' My invention relates to car-trucks, andplar- :d and combinations of devices hereinafter described, and defined in the claims. y K

, 'In the accompanying drawings, which illus trate my' invention, like characters indicate like parts throughout the lseveral"views.

a5. y'Figure 1 is a plan view ofthe improved truck, 4some parts Abeing broken away" and some parts being sectioned on the line mv o'f Fig. .F ig. 2 is side elevation of the truck,

I someparts being shown diagrammatically and 3 ,somev parts being removed. Fig. 3.isa trans'- .verse vertical section taken approximately on the irregular line a" 11:3 of Fig. 1, and Fig. '4 is a vertical section taken approximately on'thef `numeral 2the trussed side frames ofthe truck, -Which trussed side frames include laterallyspaccd pairs of bolster-columns v3', interposed between fthe npp'ertand lower -bars of said: ,4c frames and rigidly secured thereto by means "of-vertical column-bolts f1. Thebolstencol- .umns 3 at their bases are formed with angu;

laffianges -5, to which are bolted or oth-l. erwise'rigidly secured the ends of angle-'ironA LSte-bars 6 and the` ends of the reinforcingplate 7, which cooperates withA ,the saidtielbars 6 .to form a channel-like transom, rigidly tying together the two'side vframes of the n Resting on the inturned Hang-es of the ASi@ itieibars. and on the intermediate portion of truck.-

.'-The invention consists of the novel devices i VseatslQof the latter fand concave seats of the `said bearing-plates 15. As sh ltop plate of thejbolster 13., andthe said plates the plate 7, just overthe lowerbars of the side frames 2, are banlike spring-bases 8, upon which in the construction illustrated are rested multiple double elliptical springs 9. Resting upon each set of springs 9 is a combined 55 springcap Iand roller-base 10, the ends ofwhich--are notched or recessed to afford guidelugs 11, that embrace the adjacent parallel and vertically-disposed sides 3 of the bolstercolumns 3. In the construction illustrated thesaid combined caps and basesY 10 are formed each with a pair ofconcave 'rollerseats 12. The lowerl bearing-blocks 9 of the springs 9 rest in depressions formed in the Spring-bases 8, while the upper bearing- 65 blocks 9n thereof rest in pockets formed in the under sides of the combined' spring-caps and roller-.bases 10. 'The truck-bolster` 13, which isV preferably of cast-steel, is formed with sidefianges that extend from the central' portion of the ends thereof'with but slightly-'diminished vertical dimensions and `near t e ends of the said bolster are formed with elongated passages 14, through which the ends of the combined 75 spring-caps and roller-bases 10 work loosely. Thev said passages or slots 14 are of such length that theywill permit the' required endwise .movements of the truck-bolster transversely offthejtruck.

. v 8c Upper.- ro'ller-bearing plates 15 are. applied lto the end portions of they top plates of the bolster 13 immediately over the combined l lspng-caps and roller-baseslO, and bearingg g-.The numeral 1 indicates the wheels, andthe rollers 16 areinterposed between the concave own, shimminiz,r blocks or plates 17 are directly interposed he-v tween -said roller-bearing' plates 15 and the 9 15 and the top plate of the bolster 13, and the said .plates 15 and shimmingblocks 17' are `held ,in position bythe side flanges of the bolster and by retaining-lugs 18'and'18, formed 'won the top'plateof the bolster.

Atits sides outward of the bolster-columns ,the truck-bolster 13 is Vformed with stops 19,

which engage-with the outer surfaces of the bolster-colmns to limit the extreme movementof the'bolster transversely of the truck. `we

devices afforded by the rollers 16 andcoper'- ,ating bearing-plates 10 and 15.

that the truck-bolster islocked against endl3.o wise displacement by the so called cdm- Aplaced lin working positions. must of course be placed inworking position slid down onto the bolster-columns.

At its extreme ends outward of the'side frames of the truck thebolster is formed with raised bearing lugs 'or' surfaces 20, which afford socalled outside, bearings for thec'ar-body.

'(Not shown.)

In placing the. combined' spring cap and roller-base 10. in working positionl it is first slid through the perforations 14E-in thefianges of the bolster 13, and the rollers 16, upper roller-bearings 15,-and 4shimming-plates 17 are The springs 9 islocked in working 4position with freedom for vertical Aup-and-down movements under theyielding actions of the springs and fora limited endwise movement transversely of the y truck under the action of the lateral-motion It is evident bined spring-caps and roller-bases 10 and that the latter are in turn locked to thebolster-columns.

` -Hitherto holsters have been spring-supportedv with freedom for movements transversely of. the truck; but asthe combined spring-caps and roller-bases which were guided for v'ertical'movements by the bolster-columns were passed entirely below the ends of the bolster` 40" it was necessary to greatlyv reduce the thickness or vertical dimension of the ends ofthe bolster. The present-demand for cars of very` i large carrying capacity makes necessary the bolster.

tures above pointed out and which 'are incilprovision of truck-bolsters of very great strength. My present invention makesit possible to carry down the flanges or sides of the truck-bolster at its ends or near its ends ma. terially below the combined spring-caps and roller seat or base, thereby to give the re-` quired strength to the end portions of the Furthermore, the interlocking feadent to passing the combinedsprng-'cap and roller-base through the side fiange of the bolster are i themselves important.

The side bearings 20 located outside the truck side frames, givespthe widest possible as described.

base of support to the car-body and are especially desirable whenv used to support wide car-bodies, such as are lately coming into'quite general use. 1

From what has been said it will of course be understood that the devices described are capablenof modification within the scope of my invention as 'herein set forth and claimed.

ing bolster-columns, of abolster, and devices supporting said bolster from theqsides of the truck-frame, with freedom for movements transversely thereof, said devices involving bearing-plates locking said bolster to saidA bolster-columns, substantially as described. f i. 2., The combination Withatruck-frame hav-v ing bolster-columns, of apbolster working be'- tween saivd bolster,-columns,a combined springcapand roller-base spring-supported from the sides .of the truck-frame. and workingl vthrough said' bolster, and engaging said `bol ster-columns; and movable vertically thereon, substantially as described.

' 3. Thyecombihation with a truck-frame havingjbolster-columns, of a bolster having at its ends slotted side flanges, and lateral-motion, devices involvinga pair of roller-bearing lplates and interposed rollers, one of which" plates is applied to said bolster, and the other What I claim, and desire to secure by 'Letters Patent of the United States, is as followsz' 4 4 1. rlhe combination Withatruck-frame havy `of which is supportedfrom the adjacent side of the truck-frame and projects through Ithe slots of said b1 lster side Ganges," the projecting ends of y wiich engage the bolster-columns, and are guided thereby, substantially `cli-f rame ,l 4.
